Achal Agrawal, Research-Integrity Sleuth From India, Among ‘Nature’s 10 People Who Helped Shape Science In 2025’

The recognition by Nature has come just three years after Dr. Achal Agrawal began raising awareness about and reporting on research-integrity violations by Indian researchers through the Indian Research Watch (IRW), a volunteer-run non-profit organisation he founded in November 2022

India Hypertension Control Initiative: Only 44% of one million on treatment in 15 States had blood pressure under control

The IHCI study found that individuals aged 45-54 years had a higher risk of uncontrolled BP compared with those aged over 55 years. And compared with females, males had a higher risk of uncontrolled BP, and those with diabetes exhibited a higher risk. Also, individuals who were already on treatment at the time of registration had a higher risk of having uncontrolled BP

CSIR-IGIB’s CRISPR genome editing system: Raising the bar with 1,300-fold higher specificity, strong on-target editing

In a detailed interview to the Science Chronicle, Dr. Sundaram Acharya formerly with CSIR-IGIB and currently a JSPS postdoctoral fellow at the University of Tokyo, and co-inventor of enFnCas9, explains how and why the indigenously developed CRISPR genome editing system using the enhanced FnCas9 (enFnCas9) variants fare better than the existing Cas9 tool — about twice the DNA cleavage speed, a nearly 3.5-fold broader target range in the human genome, and much stronger editing activity with excellent genome-wide specificity

Four major, extended droughts likely caused the Indus Valley Civilization’s collapse

A study by IIT Gandhinagar has linked Indus Valley Civilization’s collapse to four severe droughts lasting for 88-164 years between 4,400 and 3,400 years ago with up to 20% reduction in rainfall, reduced river discharge of over 12%, together with 0.5 degree C warming

Researchers Uncover Genetic Markers Associated with Preterm Births in Indian Women

The study has identified 40 genetic variants/mutations that are associated with preterm births in Indian women, with one mutation being strongly associated. The study also found 66 genetic variants that can help predict which women are at higher risk for preterm birth

Suhani Chauhan: 14-Year-Old Hyderabad Artist Walks Tall With Four Journal Covers In Five Years

If acceptance of a manuscript by a journal is a time for celebration for scientists, so is the acceptance of a cover image for artists. Four journal cover images in five years is a huge achievement for anyone, more so as Suhani is just 14 years old and is in class 9

Nipah Virus: NIV Researchers’ Assertion Of Aerosol Transmission Not Backed By Evidence

While ARDS patients with cough and respiratory distress are very likely to expel Nipah virus into the air, there is no hard evidence to suggest that patients generate virus-laden aerosols that can “travel greater distances and remain suspended in the air for extended periods” and infect others

Camouflage, Warning Colouration: A Large-Scale Global Experiment On The Success Of Prey Defense Strategies

While warning colouration fared better in environments with low predation intensity, camouflage strategy helped when camouflaged prey species were less common and when light levels were low. Climatic seasonality had no effect on predation risk, and predation was not lower for warning-coloured prey at lower latitudes
